A) 0.98
B) 3
C) 4
D) 7
Correct Answer: D
Solution :
\[\cos \theta =0.96\] \[\sin \theta =\sqrt{1-{{\cos }^{2}}\theta }=\sqrt{1-{{(0.96)}^{2}}}=\sqrt{1-0.9216}\] \[=0.28\] \[\tan \theta =\frac{\sin \theta }{\cos \theta }=\frac{0.28}{0.96}=\frac{7}{24}\] \[\frac{1}{\sin \theta }+\frac{1}{\tan \theta }=\frac{100}{28}+\frac{24}{7}=\frac{100+96}{28}=\frac{196}{28}=7\]You need to login to perform this action.
